Question Infocus 4805 only projecting in Black and White

A mutual friend is selling his Infocus 4805 for a really good price, the catch is that the color is not working. It only projects in black and white. He said he has spoken to infocus and the problem was that the color element was out and that its an easy, cheap fix.

I wanted to know if any other people here have had this problem or know of it and had any experiences in fixing it. Is this a common problem for projectors in general and can it be fixed easily by me?

Thanks in advance.

Easily would require some context. What would be easy for me may be a real bitch for you. It's probably the color wheel assembly and should not be a killer job. If it is a good enough deal and you want a PJ, go for it. Bear in mind it is not a HD unit with 854x480 resolution and the street price is under $1,000.

Thanks for the quick response. He wanted to sell it for about $150. How much does a color wheel assembly usually go for? I would mainly use this to watch movies and play video games occasionally so i figured if fixing it would be under $100 i would have gotten a good projector to enjoy watching movies on and later i could move up to a higher end HD unit if i enjoy this one.

Thanks again for the response.

This might get you started.

You have checked the user controls? It is possible to turn the color "off " by lowering the saturation control to 0.

BTB, the lamp alone for the sp4805 is about $325

The unit is not serviceable except in Kentucky...

While Infocus HQ is in my neck of the woods, they are usually pretty tight lipped when it comes to getting parts out to a DIY'er.

Good Luck

Although it's possible that saturation was turned down to zero, it sounds like the color wheel...

I doubt replacing will cost $100 however so if you're not interested in spending a total of $400 to $500, it might not be worth it.

What connection are you using? Have you checked your video card to see if it's setup for "clone" monitor use, otherwise you have to configure.

Both my hp and gateway laptops would disable their screen when sending to the projector. And both laptops have the ctrl+F4 that toggles the video between the display and the vga out, no need to go into display properties if you have those kinda features on your function keys.

That's assuming he's using the VGA connection...that's why I asked. If it's s-video, which many laptops have...the F4 function is useless.
